Prepare areas that will join together on each liner by cleaning well. Place 3" double sided tape on bottom liner, remove tape backing, lay second liner over taped area, completely sealing liners together. Finish pond liner bond with 6" single-sided tape sealer over full seam length. Works well with EPDM rubber and PVC pond liner. Splice tape is not intended for indoors use. 3" x 25' length.
